Application July is, 1941 ,-Scrial No. 402,91 1 l 1 Claim. (01. 94-15) Thi invention relates to road markers and deals more particularly with markers for the guidance of both vehicular and pedestrian traific. The main object of the invention is to provide a road marker'which may be set and embedded into the surrounding pavement in a manner to obviate displacement due to the stresses and forces caused by vehicles passing thereover.

Another object of the invention is to provide a marker which is so formed that a plurality thereof may be arranged'in interlocking association to form a trailic guiding line or a surface having significance to motorists and pedestrians. A further object resides in the provision of a road marker provided with means for effectively keying said marker in the surrounding pavement without resort to separate and special plates, hooks, or bolts commonly employed for this purpose.

A still further object is to provide a road marker which i practically indestructible despite the great forces to which it is subjected and compressible to some degree to yield to said forces, the invention contemplating the use of a material which also imparts non-skid properties to the marker, said properties also obviating slipping of pedestrians thereon.

The foregoing objects and other objects, fea-- tures and advantages of the invention will be haveipainted or formed thereon certain markings or indicia such as shown at 13. The bottom surface H of the marker is preferably formed I together with the grooves l5, serve to obviate lateral displacement of the marking in its surrounding medium. This medium, shown at l8, may be concrete, asphalt, cement, or any of the well-known materials used on streets, roads, and highways.

As shown in Figs. 1 and 2, this form of the invention is formed as a block having castellated sides. On two adjacent sides, the castellations tform alternate tenons l9 andrecesses 20. On the other two adjacent sides, they form the alrternate tenons 2| and recesses 22. In this man nr, the opposed sides of the marker are different in that the tenons of one side are aligned with the recesses of the opposite side. The purpose of this arrangement becomes apparent from perusalof Fig. 1 which shows several markers arranged in interlocking relation to form a line of such markers. The tenons [9 of one marker fit into the recesses 22 0f the adjacent marker Fig. 2 is a perspective View of a preferred form of road marker.

Fig. 3 is a cross-sectional view thereof, taken along line 33 of Fig. 1.

Fig. 4 i a sectional view of an alternate form of road marker.

Fig. 5 is a perspective view thereof.

Fig. 6 is a similar View, as seen from the bottom, of yet another form of road marker;

respective recesses 22 and 20 should'the arrangement be transverse to that shown in full lines.

It is obvious that a marker l0 may be set into the pavement it! without reference to other markers, in which case the tenons and recesses thereof with the recesses 211i and 22 to provide the tenons l9 and 2| In this manner afurther effective keying means, comprising particularly the lower tenons Hi and M is provided to prevent undesired upward displacement of the marker from its surrounding medium.

It is preferred, however,

be not unduly limited by the instant specific disclosure which is for explanatory purposes only.

I claim: A road marker comprising a substantially square-shaped block adapted to be set into pavement and with its substantially fiat surface flush with the surface of the pavement, and means on said block having keying engagement with said pavement and adapted to interlock with similarly shaped adjacent blocks, said mean comprising spaced pairs of alternate tenons and recesses provided between the surface and underface of said block at the peripheral side walls thereof, a groove extending between said pairs of tenons and lengthwise around said side walls of said block, the tenons on one side wall being alignedly arranged with the recesses on the opposite side wall, said pairs of tenons :being coextensive with one another, and one or more projections provided on said underface of said block to preventdisplacement of said block at it location in said pavement.
